PUG-MILL.

SPECIFICATION forming part of Letters Patent No. 388,167, dated August 21, 1888.

(No model.)

To all whom, it may concern:

Be it known that l, HENRY WooneocK, of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Improved Tempering Pan, Pug Mill, and Brick-Machine Combined, of which the following is a full, clear, and eXact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my invention. Fig. 2 is a broken side elevation of the same, and Fig. 3 is a sectional elevation taken on the line a: as of Fig. 2.

The invention will first be described in connection with the drawings andthen pointed out in the claims.

A represents the base of the machine, on which is mounted the steanrcyliuder B and superstructure O, which latter supports the receptacle D, in which the clay is worked and tempered. This receptacle is formed at the top with a circular pan, (2, from the bottom of which projects the cylindrical mill d, in the bot-tom d of which is formed thetwo passages f f, through which the clay drops into the hopper E below. In the center of the pan d and mill d. and also in the center ofthe 110pper E, is the vertical shaft F, stepped at its lower end upon the central block,F, in the said hopper E. The upper end of the said shaft F isjournaled in the cross bar or plate G, secured to the upper edges of the pan (1, and t0 the said shaft, near the said plate G, is secured the spider-frame H, the arms h of which are provided with the blades 7t, and one of said arms is provided with the diagonally arranged plate 76, which serves to scrape the clay from the pan (1 into the mill (7,. In said mill the shaft F is provided with the arms t' i for agitating and working the clay, and below the said arm is secured to the shaft the propeller J for forcing the clay through the passages f to the further agitated and worked by the second propeller J, which also forces the clay through the passages m in the bottom of the hopper into the boxes K K.

In each box K is placed a follower, L, connected to the same piston-head M in cylinder B by pistonrods L If, so that both are operated at the same time by a single steam-cylin der. Each follower L is provided with a plate, N, at its upper edge to close the openings at at the bottom of the hopper E when the followers are thrust forward to the position shown in dotted lines in Fig. 2. The followers force the tempered clay into the mold-box of a brickmachine (not shown) connected to the exit ends of the said boxes K K.

The shaft F is to be revolved by suitable gearing or by a pulley, 0, so that the clay will be first worked in the pan d, and then in the mill d,aud finally in the lower hopper, E.

P is the lever for operating the slide-valve of the steam cylinder B.

Having thus described my invention, what I claim as new, and dcsireto secure by Letters Patent, is

1. In apug-mill, the receptacle D, formed with the pan (1 and mill (2, below thcsame and of less diameter than the pan, in combination with the shaft F, arms h, and blades It, to work in the pan, the arms t i, to work in the mill, and the propeller J, attached to the shaft below the arms it for forcing the clay out of the mill, substantially as described.

2. The receptacle D, formed with pan d and mill (1, and the hopper E and receptacle K K, in combination with the shaft F, provided with arms It ht', and propeller J in the receptacle D, and the propeller J, arranged to work in the hopper I substantially as described.
